spectacles and eyeglasses, and has for its ob ject to provide animproved construction of nose guard or clamp.

My invention comprises a main blade or guard and a supplemental orauxiliary guard thereon adapted to anchor the main guard againstdisplacement from the nose. The principal object of my invention is toprovide means that will automatically raise up the flesh in front of thesupplemental guard thereby tending to retain the guard in place on thenose and retarding displacement therefrom.

Another object of my invention is to provide nose clamps or guards whichare more or less resilient or yielding whereby they will easily andcomfortably adapt themselves to the nose.

I Vith these and other objects in view,'the invention consists in thenovel construction and arragement of parts hereinafter de scribed,delineated in the drawings and specifically claimed, it being understoodthat changes properly falling within the scope of what is claimed may bemade with out departing'from the spirit of my invention.

Similar numerals of reference are emdenote corresponding partsthroughout the several figures of my invention.

main guard.

Patented July 16, 1912. Serial No. 621,358.

guards in place on the nose, the nose and ridge of flesh in front of theauxiliary guard being indicated by dotted lines.

Referring Specifically to the drawings: A pair of'lenses 1 are connectedin the usual manner by a bridge 2 and lens clip Nose guards 01' clamps4: are carried on theends of levers 5 which are pivoted on the bridgeends at 6 and are operated by handles of fingerpieces 7 The nose guardsare impelled toward each other by springs 8 which operate on the levers5, being wound about the pivot 6.

The structure above described is the usual finger piece eyeglass and iswell. known in the art. To the well known guard above described I add asupplemental or auxiliary guard 9, the face of which is disposed at anangle to the face of the main guard st in such a manner as to tend toraise a ridge of flesh in front of its free edge when in place on thenose, as indicated in Fig. XIII. The auxiliary guard may be madeintegrally with the main guard as shown in Figs. III and X'II or it maybe a separate piece secured to the 'main guard as shown 'in Fig. XI.Where theauxiliary guard is made integral with the main guard an arm1.0, Fig. III is provided between the main and auxiliary guards. Thisarm is then bent and looped so as to dispose the auxiliary guard at anangle with the main guard as shown in Figs. X and XII and at the sametime provide a resilient fold 11, Figs. X and XII, tending to press theauxiliary guard toward the nose. If desired, although it is notnecessary,:a stop 12 may beused to limitthe outward movement of theauxiliary guard; this stop comprises a tongue of metalintegral with theauxiliary guard and bentso as to forma hook engaging a portionof the Themetal from which this stop is fashioned is pliable and consequently itslength is adjustable by bending to accommodatevarious outward positionsof the auxiliary guard. If desired the auxiliary guard may be madeseparate from the main guard and securely attached thereto as shown inFigs. VVI=I-VIII-IX and XI.

In Fig. V the auxiliary guard is hinged or pivoted to the main guard anda tongue 13 cut from the main guard acts as the resilient memberpressing the auxiliary guard toward the nose.

The modification shown in Fig. VI is similar to the constructionindicated in Fig. V with the exception that the auxiliary guard isintegral with instead of hinged to the main guard.

The auxiliary guard in Fig. VII is hinged to the main guard as in Fig. Vbut the in tegral tongue 13 is replaced by an independent spring 14.

Figs. VIII and IX show two modifications wherein the auxiliary guardsare riveted to the main guard. The auxiliary guard in Fig. VIII extendsfrom its attachment directly toward the front edge of the guard, whilein Fig. IX it extends first rearwardly, then forwardly forming aresilient and adjustable loop similar to loop 11 in Fig. X.

In operation the resilient member of the guard tends to force theauxiliary guard into intimate contact with the nose, the auxiliary guardbeing so angled that its front edge will tend to dig into the nose andraise a ridge of flesh in front of it as shown in Fig. XIII. When theguard is displaced forwardly on the nose the resilient member causes theauxiliary guard to follow up the contour of the nose and constantlyresist displacement by its front edge digging in. The auxiliary guardswill also tend to tighten their. grip on the nose when displacedforwardly due to the method of attaching the rear side of the auxiliaryguard to the main guard, the front edge catching in the flesh of thenose and opening out the angle between the main and auxiliary guard,causing the free front edges of the auxiliary guards to approach eachother.

The auxiliary guard may be faced or not as desired. Fig. IV shows indotted lines a xylonite pad 15 attached to the auxiliary 'guard. Thispad is shown in section in Figs. VVIVIIVIIIIX and X.

I have shown a main guard having a perforated portion, wherein theauxiliary guard is located, but it is not necessary to so perforate themain guard as the same effect can i be produced by attaching theauxiliary guard in similar manner to a non-perforated main guard. I havealso shown my guard applied to finger piece eyeglasses but it may bealso applied to the other forms of eyeglasses and spectacles whereinnose guards are used.

Various methods of arranging and placing the auxiliary guard may bedevised without departing from the spirit of my in vention. I,therefore, do not desire to be limited to the exact details shown.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The combination with a main guard, of an auxiliary guard having itsrear edge connected to the main guard to permit of relative movement ofthe main and auxiliary guards, said auxiliary guard having free frontand end edges and means for resiliently forcing the front edge of theauxiliary guard outward relative to the main guard.

2. The combination with a main guard, of an auxiliary guard attached tothe main guard to permit of relative movement of the main and auxiliaryguard, said auxiliary guard having free front and end edges, means forresiliently forcing the front edge of the auxiliary guard outwardrelative to the main guard, and means for limiting the movement of theauxiliary guard.

3. The combination with a main guard, of a supplemental guard carriedthereby, and means for resiliently forcing the forward edge of theauxiliary guard outward relative to the main guard a greater distancethan the rear edge of the auxiliary guard.

4c- The combination with a main guard, of an auxiliary guard supportedposterior to the anterior edge thereof and mounted for yielding movementrelative to the main guard, and means for forcing the forward edge ofthe auxiliary guard outward relative to the rear edge thereof.

5. A nose guard for spectacles and eyeglasses comprising a main. guardhaving a perforation, an auxiliary guard in the perforation andresilient means uniting the rear edge of the auxiliary guard with themain guard.

6. A nose guard for spectacles and eyeglasses comprising a main guardand an auxiliary guard facing and disposed at anangle to the main guard,resilient means uniting the rear edge of the auxiliary guard with themain guard and means to limit the outward position of the auxiliaryguard.

7. The combination with a main guard, of

an auxiliary guard disposed at an angle to the main guard, meansattached to the aux- 1l1ary guard posterior of the anterior edge thereoffor connecting the same to the main guard, and means for yieldinglyholding" the forward edge of the auxiliary guard outward relative to themain guard.

8. In spectacles and eyeglasses a blank for a nose guard comprising aperforated main guard section, an auxiliary guard section, a

tongue uniting the main and auxiliary guard sections and a tongueextending beyond the auxiliary guard adapted to be bent into a stop.

9. A nose guard for spectacles and eyeglasses comprising a perforatedmain guard, an auxiliary guard within the perforation of the main guard,and an integral tongue extending from the rear edge of the auxiliaryguard to the main guard substantially as shown and described.

10. A nose guard for spectacles and eyeglasses comprising a perforatedmain guard, an auxiliary guard within the perforation of the main guardand a resilient integral loop extending from the rear edge of theadapted to hold the auxiliary guard ex auxiliary guard to the main guardsubstantended beyond the main guard. 10
